METHOD AND APPARATUS FOR MARKING ARTICLES.

Application filed September 24, 192 1.

The present invention relates broadly to liquid coating apparatus, and more particularly to a method and apparatus for applying a designating mark to articles of manufacture, such as pipes, rods and the like.

in order to enable the product of one manulacturer to be easily distinguished from that of another, it desirable, under present trade conditions, to apply certain charac teristic marks thereto. The present invention l as particularly for its object the amp plication of a spiral stripe to pipes and rods. The invention further has for its object the provision of apparatus for feeding the paint or oth r coating material to a carrier or ap-- plying device, and for keeping the coating material thoroughly mixed and as free from foreign particles as possible.

In the accompanying drawings We have shown, tor purposes of illustration only, certain preferred en'ibodiinents oi the pres ent invention, it being understood that the drawings do not define the limits of the invention, as changes in the construction and operation as disclosed therein may obviously be made Without departing from the spirit of the invention or scope of our broader claims.

In accordance with the resent invention their lining is preli -rrably effected by provldu a line of marking material and rolling the article to be marked thereacross with the longitudinal axis oi the article main-- tained at an angle 011? less than 90 to the axis of the marking line. While this object may be accomplished in a number of difien ent Ways, we have found that desirable resuits may be obtained by PI'OVllZlll'lg supports 2, as illustrated in Figure 1, spaced. a dis tance which is substantially equal to the length of the article to be marked whereby the article may be easily supported and rolled thereon during the marking opera tion. Positioned between the supports 2 is a pot or trough 3 which may, if desired, he COl'lS'lll'llCtGtl in sections, as illustrated, and adapted to contain thecoating material. Suitably journalled at its opposite ends in the end Walls of the pot 3 is carrier 4- adaptod to transit-2r the coating material from the pot to the article. This carrier may conveniently be constructed in the form of a roll which is so n'iounted that a portion oi its periphery at all times projects above the upper edge of the pot and also lies in a plane whicl'i is slightly higher than the plane of contact betu'eei'i the supports 2 and the articles. The pot 3 is also arranged that the axis of the carrier mounted therein intersects the longitudinal axes oil the supports 2 to form. su 'ipleniental angles having dit- By reason of this construction, it will be p mrent that ii the articles illustrated in the ljlrawings as comprising pipes or rods P are rolled on the supports 2 from the station A to the station B their peripheries will be in contact with a portion of the carrier 4; whereby coating material Will be transferred from the carrier to the articles. By reason of the angularity maintained between the carrier and the articles,

this material will be transferred to the articles to form a spiral mark or stripe S.

In order to continually provide a suiit cient supply of coatmg material we have found it desirable to rotate the carrier 4.

'This may be accomplished by providing a maintaining the coating material Within the pot in a constant state of agitation, and also for effecting the removal therefrom of heavy foreign particles. These functions may be accomplished by providing the portion of v the shaft within the pot with a spiral blade 11v acting upon rotation of the shaft as indicated by the, arrow at to produce a movement of the coating material in the direction. of the arrow 1) Preferably, the edge "of thespiral conveyor is in contact: with gears 14. With the gearing arrangement i the bottom of the pot whereby any foreign Will have a still slower speed of rotation than the shaft 13. The level of the coating material in the pot is maintained high enough so that at least a portion of the carrier dips into the same at all times. During the rotation this coating material Wilt become uniformly distributed over its sur face-and ai'iysurplus will be effectively r moved by suitable means, such as doctor blades 20; For convenience in filling the pot as may be required, it may be provided with an, off-set ures l and 6. I

The carrier may be constructed in the form of a tube, as indicated in Figure 8, with the ends carried by stub shafts projecting thereinto. To prevent sagging any as clearly shown in Figdesir-ed number of intermediate bearings 23,

tirely, the bottom shaft lllrbeing relied upon to effect all of thenccessary agitation and' removal of foreign matter.

In some cases it may be desirable to dispenseivith theuse ofa single pot as before described and provide a construction asin cheated in Figure 2,

in whichaplurality of naterialxthereon will. be moved. lengthwise relatively ,smaller pots 3 are provided; In t such anevent, the carrier 41- of each pot of the pot and deposited in a collecting chamberlQ provided at one endthereof. This chamber may be formed with a clean out'opening wherebythe foreign material ma be removed at will, as will be Well un erstood. f p

Intermediate the shaft 10 and the carrier 4 may beprovided a second shaft 13 having a construction similar to the construction of the shaft 10, just described. In order, however, to rotate the shafts 10 and 13 in dif- V ferent directions to eli'ecta more thOFGilrJl agitation of the coating material, the shafts are directly intergeared by means of, the

lustrated, it Will be apparent that the shaft 10 will be rotated at a higher speed'than the shaft13, thereby tending to prevent any pigment from settling out from the coating material and, at the same time, rotating the intermediate shaft 13 at a speed slow enough to prevent splashing of the coating material over the sides of the pot.

For rotating; the carrier 4 there may be provided a gear 1i) onthe shaft 13 adapted to mesh with a gear 16 which is keyed to the hub of a gear 17 loosely journaled on the shaft 10. The gear 17 in turn meshes with an idle gearl8 on the shaft 13 and through the idle gear drives the gear 1.9

' splined to the carrier shaft. This gear train may have a suitable driving connection 8" with the driven shaft The angularity of the pots may be varied, if desired, in

marking articles of different diameters whereby the individual lines formed by each of the marking devices may come into rcgistration and form a continuous spir al.- 1

other cases the pots may be set at an arbitrary angle and the individual marks formed a by each of thecarriers relied upon to p'roduce the effect of a continuous spiral.

With any form of our invention, the highest portion of the carrier or carriers prorvided. will preferably be slightly above the supporting surface of the supports 2 so that an eifective contact between the carriers and the articles is insured.

The advantag'es of the present inventionarise from the provision of a method and apparatusby means of Whicha spiral may be effectively appliedto certain articles of manufacture.

Further advantages arise from the provi- '1, lnthe method of marking articles, the

steps of rotating an article in contact with will preferably be such that the carrier a coated roll and causing the contacting por- 'tion of the roll to move along the article while in rolling contact with each other to produce a spiral stripe on the article.
